It's true though.
Literally every interaction I've had with Trump supporters is the same. It's anecdotal, sure, but I've dealt with many, my family is made up of many, and they all seem to be a carbon copy of one another.
They hate immigrants, full stop. They try to play coy by saying they love legal immigrants, but that facade falls apart when they try to interact with someone who can't speak English. I've seen it happen over and over.
People who immigrate to the United States should speak English. Why is this considered offensive?
